In versions below 1.0.20, an error in command parsing makes it possible to bypass the Claude Code confirmation prompt to trigger execution of an untrusted command. Reliably exploiting this requires the ability to add untrusted content into a Claude Code context window. This is fixed in version 1.0.20.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-78"],"references":["https://github.com/anthropics/claude-code/security/advisories/GHSA-x56v-x2h6-7j34"],"products":["anthropic:claude_code"],"source":"nvd","synced_at":"2026-10-19T22:06:45.861874017+00:00"},"epss":{"cve":"CVE-2025-54795","score":0.01044,"percentile":0.64122,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-x56v-x2h6-7j34","url":"https://osv.dev/vulnerability/GHSA-x56v-x2h6-7j34","summary":"Claude Code echo command allowed bypass of user approval prompt for command execution","modified":"2025-08-05T17:10:38Z","packages":[{"ecosystem":"npm","name":"@anthropic-ai/claude-code","purl":"pkg:npm/%40anthropic-ai/claude-code","ranges":["<1.0.20"],"fixed":["1.0.20"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
